You have to be careful when bargaining these days. You never know who you may be dealing with.

On last night's episode of "Gossip Girl" Blair enlists Chuck's help to bring down Vanessa. Usually, she wouldn't care about a lowly Brooklynite, but Vanessa is using the picture of Marcus and Catherine to blackmail her. Blair wants Chuck to humiliate Vanessa in return for a steamy night.

You see, Vanessa actually cares about more than Prada and Gucci and is trying to save an old hotel from being demolished. Chuck shows up and offers to buy the building and manages to win Vanessa's trust. He invites her to the van der Woodsen/Bass family party that night where he intends on seducing and humiliating her.

After seeing the hotel and speaking with Vanessa, however, Chuck has a change of heart. When his father tells him he can't buy it and sees it as a mistake, he tries to convince him that it's good for business. Chuck actually cares about something. Like usual, however, his dad treats him like the scum he thinks he is. Vanessa sees the interaction and tells Chuck that he doesn't deserve to be treated that way.

For once, we're seeing the human side of Chuck. It's peeked out a few times in the past, but last night he had a vulnerability to him. We saw a young boy trying to win over his father while trying to figure out what to do about the girl he thinks he loves. I actually even think he cares about Vanessa, despite what's happened in the past.

The CWVanessa is the subject of a deal between Blair and Chuck.

But Blair ruins the love-fest when she tells Vanessa about her deal with Chuck, which has been called off because Blair doesn't care about Vanessa anymore -- which is what she tells Chuck. She really can't handle seeing the man who's supposed to be chasing her cuddling up to another woman.

Vanessa runs to tell the hotel owner what happened. Blair tells Chuck to meet her in her room in an hour. She managed to delete the photo of Marcus and Catherine from Vanessa's phone and declares that she lost their bargain and Chuck won. Chuck goes back to the hotel and tells the owner that he's still going to buy the place, now he just has to figure out how, and then returns to Blair.

In one of the sexier scenes in GG history, Blair is wearing lingerie and the two start kissing. But after a few seconds, Chuck stops and tells Blair he doesn't want her now. It's time for her to start chasing him.

Blair should have known better before making deals with the devil. Then again, she is a bit of a devil herself. I'm not sure who's worse here, but one thing is for sure, no one beats Papa Bass in the evil department, at least not when it comes to his son.

Aside from the Chuck-Blair-Vanessa love triangle, Bart and Lily imposed new rules on Serena, Eric and Chuck and Serena is not happy. During their party, she starts telling a magazine how Lily is a bad mother who followed whatever her husbands/boyfriends did.

Nate and Dan's friendship is growing, until Dan realizes that Nate is living in his foreclosed old house while his mother is in the Hamptons. When he tells Nate that he knows, Nate gets upset and tells him they're not really friends. But Dan, the human being, finds him and brings him to stay at his place.

Dan and Serena share a sweet moment toward the end of the episode while both are waiting for Nate. Serena tells Dan that she's glad Nate has a friend like him during this difficult time. Then, Bart shows up to take her home. It's inevitable that the two will get back together, it's just a matter of how long.

It looks like next week is going to be a scorcher in "Gossip Girl" land as Jenny becomes the devil. I wonder who'll be next.
